Wildcard Performer

This class gives the advantage of prepared patterns.

Example:

<?php

    use JayBeeR\Wildcard\WildcardFactory;
    
    $factory = new WildcardFactory;
    $testPostfix = $factory->create('*test');
    
    if ($testPostfix->match('this is a small test')) {
        
    }

The strategy behind it is very simple:

Every token and phrase you have in a wildcard pattern will be split in a array structure with following information:

Token	Minimum position	Maximum position
*	0	-1 (length of subject)
?	1	1
**	1	-1 (length of subject)
?*	0	1
(none)	0	0

The array is structured like this:

[
    'following phrase'
    'minimum position' (results from the tokens)
    'maximum position' (results from the tokens)
]

Each step of this information will be check with the current subject. The found position is then compared with these.

Implementation

The following number of implementation of PHP's internal string function is needed:

Function	implements
strlen	5
substr	4
strpos	1
chr	2
